Battery stats with Standard and Extended Battery..

So, if you have two batteries, how does the system average the battery stats? They are two different animals and I doubt it's conducive to wipe the battery stats every time you want to use the standard battery or change to the extended battery.

Actually, the extended batter is a Lithium Ion Battery, it doesn't need calibration because it doesn't have the "memory" that the Lithium Ion Polymer (standard battery) does.
Lithium Ion Batteries work best with a higher charge, so just keep it charged as much as possible.
If you switch back and forth between the 2 batteries, you need to calibrate the standard battery once, then you should be able to switch back and forth without issue.

Not exactly what I was talking about..
The "Wipe battery Stats" in CWR is what I was talking about.

Wiping battery stats in CWR is part of the calibration process.
You should charge it fully while the phone is off, then wipe stats in CWR, reboot, use the phone as normal until the battery dies, then charge it fully while it's on.
After that you can switch back and forth.
That calibration technique is for the standard battery. Like I said before, the extended battery needs no calibration.

Understood, but the thing is, won't it get confused by the two types of battery?

Nope. The battery stats are only used for the Lithium Ion Polymer batteries.
The lithium ion battery has no memory. Just try to keep it fully charged as much as possible.

So, if I have a charger at my side, use it eh?

Yep yep yep.

One thing I've noticed that maybe Tivo7 can answer:
On the standard battery, when I would reboot my phone the battery life would drop. Say I was at 70% battery life, I'd restart phone and it would be at 50% or 40%..
On the extended battery, its the opposite. I'll be at 80% battery life, restart my phone, and it'll be at 100% for a few hours. And its done this half a dozen times for me. I've never actually seen the battery level do anything other than increase after a restart.
Is this phone just really bad at telling battery level? I know its difficult to accurately determine battery level (I've read that before) but this phone seems to be particularly bad at it.

That's a known issue and idk how to fix it or if it even needs fixed. I figure it just used a lot of battery to boot up.

/ninja
But yeah idk how or why that happens or how to fix it. I just deal with it.
My extended battery is usually at like 60% by the end of the day after being charged overnight then used all day.
And I charge it every night so it rarely gets below like 50% unless I do a lot of apk editing and flashing that day.

Informative thread, learning has occurred for me...
I've been running the whole calibration procedure for my extended batt for no reason... Well, NOW I know..
Thanks gents...

Same here, I've used the calibration app a few times and deleted battery data using CWM to see if it would resolve the inaccuracy problems.
Uninstalled the calibration app after I read this thread.
Also, although Lithium Ion Batteries don't have a memory effect, they do have one issue from charging:
High charge levels and elevated temperatures (whether from charging or ambient air) hasten capacity loss. Charging heat is caused by the carbon anode (typically replaced with lithium titanate which drastically reduces damage from charging, including expansion and other factors).

So it may not be best to keep it at full charge at all times. I mean, I wouldn't go out of your way to charge it all the time.

Same here.I calibrated my extended a lot of times,Now I don't have to,

[Q] First Charge on P880 Battery with stock battery and Info with an Extended Battery

Hi Folks, I recently Got a P880 but I dont know how is the process and time needed for charging for having a lifetime performance since first chage is Important
I want to know the best way to keep it with the better time to last untill the last second
the extended Battery is a Onite 4800mah battery, what is the process with thes ebattery with fisrt charge? how many time I need to charge it first time? and what other infor about Li-Ion Battery I need to know?

No One?

for what i know charging at stock battery is preety quick for me took 3-5 hours about the 4800 it maybe took 8-9 hours maybe

but for first time charge there isnt some tips like I read in a webpage where said that Wait to use battery until 0% and then charge it to 100% and after that wait 2 hours more and that`s it ,what tips you know for this? and the same process is withthe extended battery? bcuz I guess that they come pre charge but only for being calibrated right?

what i know is charge your battery to the fullest then calibrated it and then make sure your phone too 0% ( make sure you dont charge in the middle), then fully charge again, this is what i do and if you gormat your phone make sure you calibrated if the battery is allready full, this what i do maybe its diff from you but you can try

I think that I dont have a correct meaning of calibrate, I was thinking it was to fully discharge it and charged it to 100% and then wait 2 hours mre but
how I can calibrate only with a wall AC charger?(it`s brand new phone so it`s a bettery with stock pre charge which isnt good for having a normal usse at first time)

You can't. Battery calibration needs some low-level battery controller control. As we don't have that, just charge your phone, discharge it and charge it again. Do that a few times and your battery will be fully calibrated. Forget about deleting batterystats and such rubbish (read about that here..

Fully charging takes more then 2 days??

Hello,
Since yesterday my phone needs more then 2 days to completely charge? Can this be ROM related or is my device damaged?
I'm running CM10.1 with stock kernel btw.
Thanks!

No it is not normal.
But which phone do you have. In here we discuss the normal s (I9000) and the s plus (I9001)

Check your charger first. A corrupted/duplicate charger would take long enough time to charge the battery to 100%
If it's ok, Try to charge your battery in a similar device. If it charge properly, then the problem might be in hardware.
If it not charging properly in other device, it's time to change your battery..:fingers-crossed:

I tried charging the old battery and that goes really fast. At least for me it's normal. It went from about 55% to 88% in 1,5-2 hours so happily it's not device related. Seems that the new battery isn't working properly. Or should i setup something to make my device recognize the new battery?

There's nothing to setup for a new battery. Only just in first use you have to charge it continuously for about 2-3 hours to calibrate it with the device.
Try one thing, fully discharge the battery to 0% and charge it up to 100% continuously.(whatever time it takes) :fingers-crossed:
If it not helps, change the battery.

It wont decrease battery life.
The only way the battery could be hindered via charging is if you do it for extended periods of time.
For example more than 10 hours isnt good.

Thanks for clearing that. So we can charge our phone whenever we want to but be careful not to charge for too long at a stretch. Is it correct?

Yeah. I've read up on this stuff. More than 10 hours is called Overcharging. It's unhealthy for the battery and for the phone itself
The normal charge is just plugging it at any time and plug it out at any time.
And then there is healthy charge. You need to do this once a month or two.
Let the battery fall below 20-15 percent and then charge it up all the way to 100.
Also keeping it plugged in at 100% isn't recommended because we don't have smart charge (which basicly cuts of the power from the charger to the motherboard at 100% to prevent wear and tear like in some new high end devices)
Hope you find this interesting :3

Thank you. I will do some research on this myself too..

Maybe add it to the get started guide? ;3

so charge for a short time doesn't decrease the battery?
ex: charge from 30% to 50% is not wrong?

If you sleep less than 10 hours than its good. I do that when I go to school.
More than 10 is not healthy.

this becomes a problem esp if u use usb tethering

Modern firmware stops charging the phone when it's full, drains it a bit, and then will not send any juice to the battery anymore- it's pretty much impossible to overcharge unless you've corrupted or hacked out that bit of the firmware or you're overamping to begin with- or the phone and its firmware are poorly designed or executed.
This is also why your phone drops from 100 to 95% so fast when you start using it- it wasn't at 100% when it stopped charging; the firmware lies to you so you don't get mad and try to overcharge and destroy your battery or call customer service because it won't go above ~98%

Well then, I've had this phone for over a year and always charge it over the night (way over 10hours :I)

I have it... and it last longer ... like a 15 - 20% than the original.

I ordered mine too! How did you install it? Drain first the original battery? And the install? Or does Android reset the statts for the battery by itself?

I bought used Droid 4 last month. Battery seems to be in good state (2-2,5 days of light use), but every time it gets to ~40% it immediately drops to 20% (within few seconds). Is there a way to delete battery stats so it can detect percentage correctly? I tried to discharge it completely and recharge again but it didn't help.
Phone is running CM11. Any help appreciated.

if battery's charge is very low, it could take a while to show any change. Normally batteries has some charge, but who know when the battery was made and packaged, could have been a couple of years ago. I would leave connected to wall charger over night.

droid 4 doesnt require a new rear cover but it will wear out quickly if you remove it frequently. you can even keep the phone without a rear cover if youd like because the stock battery has a glue that holds it together with the phone along with the screws for the flex cable
